I’ve a 2.2 diesel, 54 plate, it’s always taken longer than expected to start, last year replaced filter with genuine Honda Bosch fuel filter, recently starting got worse, tried Wynns injector cleaner in fuel, actually ran like a dream, now won’t start at all, give little sniff easy start and she’s away. Friend used to work at parts at Honda , he aske a technician, they recon common fault in the day was high pressure fuel pump, it has a chamber that keeps the diesel in to start it, seals go and fuel runs back so starting issue. My questions are? Is the high pressure fuel pump easy to remove ( I have a donor car I can remove one from that ran perfectly) are there any other parts darts I should try from the donor car before changing the pump? Is the high pressure fuel pump just a straight swap or is their need fo recoding? Thank you in advance
